Editorial Policy of Journal of Agricultural Research 7 



If the original of an article has not been consulted the following 

 statement, in brackets, should be added to the citation : '* Original not 

 seen." If only an abstract can be cited, the word " abstract," in 

 parenthesis, should follow the title. 



Unpublished material, exsiccatae, and any citations not satisfac- 

 torily i)lacod in "Literature cited" should always be in footnotes 

 even if other references appear in a list. The only essential dif- 

 erences in the form of the list and the footnote references are the 

 following, which are used in footnotes only : Author is indented, 

 date is last item of reference, and specific reference may be made to 

 l)age, plate, etc., if desired. 



C'itaticms under ""Literature cited" should be placed in alphabeti- 

 cal order under authors' names. For convenience of reference from 

 text to list, citations are numbered consecutively. Arrangement of 

 titles under an author is chronological. Titles of joint articles are 

 placed under senior author's name, but the names of second authors 

 are arranged alphabetically, regardless of chronologj'. Authors' 

 names shoidd be separated by commas and the word "' and " used 

 before the last one. Dashes or 3-em lines are used to indicate repeti- 

 tion of name of .senior author. Anonymous titles are entered under 

 '"Anonymous," and in a list precede all author entiies. "]\Ic" and 

 " St " are arranged as if written in full, letters with umlaut ii, o, ii, 

 as if ae, oe, ue. 



In citations of books, entries should be made imder the author's 

 surname, followed by his initials, date of publication, verbatim title 

 of the work, edition (except first), pagination or volume, illustra- 

 tions, and place of publication. In footnote references the date 

 should follow the place of publication. Pagination is not given if 

 book is in more than one volume. The abbreviation " illus." shoidd 

 be used for all illusti'ative material. Places of publication should be 

 given exactly as on title page; if more than two, one or two fol- 

 lowed by [etc. J should be given, 'i'he date on title ])age is the one 

 used. If more than one volume, inclusive dates should be given. If 

 the date is supplied from copyright, preface, or from some outside 

 source, it should be put in brackets. If book is in important series 

 a note to this eirect should be made in parenthesis at end of reference. 



In citations of periodicals the author's surname shovdd be given, 

 followed by his initials, date, vei'batim title of the article, title of 

 periodical, sei-ies, volume, ])aginatioii, and the abbreviation '"illus." 

 if there are illustrations. Titles of periodicals are abi)re\iated ac- 

 cording to the list of '"Abbreviations Employed in Experiment Sta- 

 tion Record" (Department Bulletin No. l.'};^()). Series number 

 should be given in |)arenthesis preceding volume number. The
